New reference design enabled multi-gigabit IEEE 802.3 MDIO interface controller based on small, low power, MachXO3 and ECP5 families
HILLSBORO, OR August 6, 2014 - Lattice Semiconductor Corporation (NASDAQ: LSCC) the leader in low power, small form factor, customizable solutions, is helping engineers quickly implement optical Ethernet designs up to 100Gb/s with the publication of a new reference design for IEEE 802.3 Management Data Input/Output (MDIO) interface controllers.
Reference design RD1194 uses the world’s smallest, lowest cost per I/O programmable platform, the MachXO3™ family, or the new ECP5™ family. The ECP5 features the industry’s highest functional density with up to 85k LUTs and SERDES in tiny 10mm x 10mm packages. With their small size and low power, MachXO3 and ECP5 devices are perfect for implementing I/O expansion, bridging or connectivity needed to deliver Multi gigabit Ethernet applications such as CFP2/4 modules.
Designers can use the reference design to implement a simple Wishbone user logic interface that enables the user to access the PHY registers. It supports MDIO IEEE 802.3 Clause 45/22 master/slave controllers and features pre-amble pattern selection through the input port.
Lattice Semiconductor (NASDAQ: LSCC) is the leader in low power, small form factor, low cost, customizable solutions for a quickly changing connected world. From making smart consumer devices smarter, to enabling intelligent industrial automation, or connecting anything to everything in communications, electronics manufacturers around the world use Lattice’s solutions for fast time to market, product innovation, and competitive differentiation.
